Response Validation in Google Forms: The Ultimate Guide for 2024

In this article, we will show you how to use response validation in Google Forms in just a few clicks. Simply follow the steps below.

What Does Response Validation Mean in Google Forms?

Response validation in Google Forms is a feature that allows the creator of a form to set specific rules for each question. These rules must be followed by respondents in order for their answers to be accepted. If a response does not meet the set criteria, the respondent will receive a prompt to correct their answer.

Here are some ways you can use response validation in Google Forms: 

Text Validation

For a text question, you can require the answer to contain certain words or characters or match a specific format like an email address.

Example: When requesting an email address, you can set the response validation to "Text," choose "Email," which will validate that the response entered has an email format.

Number Validation

For number questions, you can set a range (e.g., must be greater than 5), require a specific number, or allow only numbers that are multiples of a certain value.

Example: If you're asking for someone's age, you could set the response validation to "Number," "Greater than," and enter "0" to ensure a positive number is entered.

Length Validation

You can require a minimum or maximum number of characters in text responses.

Example: For a U.S. phone number, you could set the response validation to "Length," "Minimum character count," and enter "10" to ensure a 10-digit number is provided.

Regular Expression

Advanced users can use regular expressions to set more complex rules for text responses.

Example: To validate a car model that starts with "F" and ends with "E," you can use "Regular expression," "Matches," and enter the pattern "^F.*E$."
